大般涅槃經集解 55.66

55.66

Sengliang comments: The above expounded the generative cause and the revealing cause succeeding one another from upholding precepts to nirvāṇa, but had not yet discerned from what cause nirvāṇa exists; hence he raises the question. Sengzong says: The intention of the challenge is to make precepts, being without a cause, permanent, and nirvāṇa, having a cause, impermanent. Baoliang says: Since precepts beforehand have no cause, they should be permanent; while nirvāṇa has liberation as its cause, so it should be impermanent.
